North is to the left in this image. The dominant galaxy on the left is NGC 5068; the galaxy on the right is NGC 5084. NGC 5084 is the flagship galaxy of the NGC 5084 galaxy group; it has an active galaxy nucleus. Also in this field is the distant Abell 1709 galaxy cluster, but at this image scale, it looks like a group of stars . There are a number of noticeable smaller or background galaxies in this field. These  galaxies are identified in the  the annotated image.  NGC 5068  is approximately 20 million light years distant from Earth; NGC 5084 is approximately 82 million light years distant; the Abell 1709 galaxy cluster is approximately 697 million light years distant.  Horizontal FOV is 88'

Image center is approximately - Equatorial 2000: RA: 13h 19m 30s Dec: -2127'33"
